SC4901 - COMBI-SYNC Secondary Side Synchronous Rectifier and Regulator

General Description

COMBI-SYNC Secondary Side Synchronous Rectifier and Regulator

Key Features

  • ‹ Single controller performs synchronous rectification ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ and post regulation Independent regulation of multiple outputs from a common secondary winding Turn on shoot through inherently eliminated Primary switch turns ON and OFF with zero current No synchronising or any other signals needed across the isolation boundary Eliminates the need for a secondary bias supply Independent soft start, ON/OFF, remote sense and current limit for each output Resistive or inductive current s.
